CellaTemp® PA 41 is a digital pyrometer featuring fibre optics to measure temperatures ranging from 700 to 3000 °C. The sensor head is housed separately from the electronics assembly. Both the sensor head and the fibre optic cable are unsusceptible to electromagnetic radiation. The optical sensor head can withstand ambient temperatures up to 250 °C without cooling. This variant is ideal for cramped, hard-to-access locations.

Caution: The fibre optic cable must be ordered separately

Features:

  • Range: 700 to 3000 °C
  • Focusable, interchangeable optics allow for precise distance adjustment
  • Precision lenses with broadband antireflection coating
  • Short wavelength spectral response
  • LED display is easy to read from a distance
  • Test current can be applied to perform diagnostics
  • Signal processing: two analogue outputs and USB / RS485 interface.
  • Sensor head and fibre optic cable for ambient temperatures up to 250 °C
